What is an OLED screen test?
An OLED screen test shows pure black, dark and mid grays, red, green, blue, light gray and a gray ramp. These screens reveal faults that are typical of OLED and AMOLED displays.
Use this test to check a phone, TV or monitor for burn-in from static images like a taskbar, keyboard or channel logo, for temporary image retention, and for uneven tint at low brightness.

How to read your results
Faint shapes that stay
Shapes like a status bar or logo that do not fade are burn-in.
Shapes that fade in minutes
Shapes that disappear after a few minutes are image retention and are usually harmless.
Pink, green or blotchy dark gray
Some unevenness at very low brightness is common on OLED.
Dots that never turn off
A lit dot on pure black is a stuck or hot pixel.

Frequently asked questions
What is OLED burn-in?
Burn-in is permanent wear where a static image has aged some pixels more than others, leaving a faint ghost image.
Which screen shows burn-in best?
Mid gray, light gray and solid colours, especially blue, show uneven wear most clearly.
Can this test fix burn-in?
No. It helps you see burn-in. Some phones and TVs have their own panel refresh or pixel shift features.
Is a pure black screen off on OLED?
Yes. On OLED, black pixels are switched off, so the screen should look fully dark.
